It's rather splendid to think of all those great men and women who appear to have presented symptoms that allow us to describe them as bipolar. Whether it's Hemingway, Van Gogh... Robert Schumann has been mentioned... Virginia Woolf, Sylvia Plath... some of them with rather grim ends.
It's not all bad. Heightened self-consciousness, apartness, an inability to join in, physical shame and self-loathing—they are not all bad. Those devils have been my angels. Without them I would never have disappeared into language, literature, the mind, laughter and all the mad intensities that made and unmade me.
